It was just an example of a task. Also, "compile to LLVM" is very much "LLVM is part of the compiler, and thus worries about registers". Compile to C is (depending on source language and exactly which definitions you use) potentially also a transpiler.

Eh, I don't really see what this term gives us... So C2Rust is a compiler too, since Rust is compiled to LLVM?

All transpilers are compilers.

C2Rust is a transpiler and a compiler.

Not all compilers are transpilers.

Graal for example is a compiler but not a transpiler.

Just like all cheese burgers are burgers but not all burgers are cheese burgers. Nobody questions the term ‘cheese burger’ because we already have the word ‘burger’.

[the-alt-one]

Yeah, because a cheese burger has cheese. What does a transpiler have? What is the common factor between all transpilers? Who decides on this layering of which languages are higher level or lower level? C2Rust doesn't call itself a transpiler, it calls itself a translator.

This term seems completely useless to me.

High to high translation. Limited lowering.

> Who decides on this layering of which languages are higher level or lower level?

You know it when you see it.

Who decides what makes a book a 'horror book'? There's no authority on that either. You know it when you see it.

> C2Rust doesn't call itself a transpiler, it calls itself a translator.

Yes a translator - a translating compiler - a transpiler.

> This term seems completely useless to me.

Not sure why the term seems to wind people up so much - it just add a little extra info.
